Loss-of-function phenotypes are predicted significantly better than random expectation. Here, predictability is measured as the area under a receiver operating characteristic (ROC) curve (AUC), measuring the AUC for each of 100 yeast phenotypes observed in genome-wide screens and plotting the resulting AUC distributions. Real phenotypes are significantly more predictable than size-matched random gene sets. At the left of each box-and-whisker plot, the center of the blue diamond indicates the AUC mean, the top and bottom of the diamond indicate the 95% confidence interval, and the accompanying solid vertical line indicates ± 2 standard deviations. The bottom, middle, and top horizontal lines of the box-and-whisker plots represent the first quartile, the median, and the third quartile of AUCs, respectively; whiskers indicate 1.5 times the interquartile range. Red plus signs represent individual outliers.
